This crash happens 100% of the time (on Linux at least), you just need
to open the configure window and click OK.
It seems to happen when the tabs are destroyed and once all the tabs are
destroyed, a final signal is sent with `index == -1`. So `debug_tab_tab`
doesn't exist anymore when this happens, so the crash.
- configure_input_player_widget.cpp: always better to use `const auto &`
whenever possible
- profiler.cpp: `ev->pos()` is deprecated, replace with
`ev->position()`, which returns floats, thus the addition of
`.toPoint()` (same as what's happening in `pos()`)
- game_list.cpp: `QString::SplitBehavior` is deprecate, use `Qt::`
namespace instead
